Zusammenfassung:	The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. In a wireless communication system according to one embodiment disclosed in the present specification, a base station may receive information about CSI measured based on a first CSI-RS (reference signal) from a terminal, determine one autoencoder among a plurality of autoencoders based on the information about the CSI, transmit information indicating an encoder included in the determined autoencoder to the terminal, transmit a second CSI-RS to the terminal, receive compressed CSI based on the information on the second CSI measured based on the second CSI-RS and the indicated encoder from the terminal, and perform reconstruction based on the compressed CSI and a decoder included in the determined autoencoder. 본 개시는 LTE와 같은 4G 통신 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G 또는 6G 통신 시스템에 관련된 것이다. 본 명세서에서 개시되는 일 실시예에 따른 무선통신 시스템에서의 기지국은 단말로부터, 제 1 CSI-RS (reference signal)를 기초로 측정된 CSI에 관한 정보를 수신하고, CSI에 관한 정보를 기초로 복수의 오토인코더 (Autoencoder) 중 하나의 오토인코더를 결정하고, 결정된 오토인코더에 포함된 인코더를 지시(indicating)하는 정보를 단말에 전송하고, 단말에 제 2 CSI-RS를 전송하고, 단말로부터 제 2 CSI-RS를 기초로 측정된 제 2 CSI에 관한 정보 및 지시된 인코더를 기초로 압축된 CSI (Compressed CSI)를 수신하고, 압축된 CSI 및 상기 결정된 오토인코더에 포함된 디코더에 기초하여 복구(reconstruction)를 수행할 수 있다.
